Serramax Serradella

Hard seeded and highly regenerative

Ornithopus compressus (yellow serradella)

In stockDownload tech sheet

WA bred new variety that is an early flowering, hard seeded, yellow serradella with a semi erect growth habit and an increased rate of hard seed breakdown which favours strong regeneration. Suited to acidic sands and sandy loams, it establishes quickly reducing early weed competition. Suitable as a permanent pasture improving soil fertility and boosting yields for subsequent crops (Yellow Flower).

Key attributes

  • French serradella for cropping rotations
  • Deep rooted for drought tolerance
  • Strong nitrogen fixation
  • Persists through cropping rotations
  • Suits acid sandy country

About this variety

Serramax is a hard seeded serradella selected for regeneration, and it is aimed squarely at cropping rotations on acid sandy country.

Serradellas earn their place on soils too acid and too infertile for sub clover, where they fix nitrogen and produce feed that would otherwise be unavailable. The limitation of the soft seeded types is that they cannot survive a cropping phase, because their seed germinates rather than waiting. Serramax is hard seeded and highly regenerative, so the soil seed bank persists through the crop and the pasture returns without resowing.

It is deep rooted, which underpins its drought tolerance and lets it draw on subsoil moisture late in the season, and it fixes nitrogen strongly for the benefit of the crop that follows.

Serramax suits acid sandplain in a mixed farming rotation, where the pasture phase has to pay its way both in livestock production and in nitrogen left behind for the cereal crop.

FAQs

What's a legume that regenerates strongly on acid sand in 300mm country?

We recommend Serramax Serradella, a WA-bred, hard-seeded yellow serradella with an increased rate of hard-seed breakdown that favours strong regeneration. It suits acidic sands and sandy loams in 300mm+ rainfall areas and flowers early, at about 95 days in Perth.

How do I get a new pasture up quickly to beat the weeds?

Choose a species that establishes fast. Serramax Serradella establishes quickly, which reduces early weed competition, and it's well suited to acidic sands and sandy loams. We also recommend a good knockdown before sowing and controlling redlegged earth mite at establishment to protect young plants.

How much yellow serradella seed per hectare should I sow?

We recommend sowing Serramax Serradella at 6 to 10 kg/ha. Inoculate with Group G/S so it nodulates well on acid soils, and sow shallow into moist soil. It's early flowering, at around 95 days in Perth, and suits 300mm+ rainfall on loamy sands to loams.

Is there a serradella that handles a bit of waterlogging?

Serramax Serradella is tolerant of both low pH and waterlogging, making it a good option for acid sandy paddocks that get wet over winter. It's hard seeded and regenerates strongly. It still performs best where water doesn't lie for long periods, and suits 300mm+ rainfall areas.

What permanent pasture legume will improve soil fertility before cropping?

Serramax Serradella suits permanent pasture and improves soil fertility, boosting yields in subsequent crops through nitrogen fixation. Its hard seed and strong regeneration mean it keeps coming back without resowing. It's suited to acidic sands and sandy loams with 300mm+ rainfall.

What legume works on low rainfall sandplain where the season cuts out early?

For acid sandplain in lower rainfall areas, we recommend Serramax Serradella. It suits 300mm+ rainfall and flowers early, around 95 days in Perth, so it can set seed before the season finishes. It's hard seeded with strong regeneration, and establishes quickly.

What should I sow with a regenerating serradella for grazing sheep?

Serramax Serradella fits well with ryegrass and other acid-tolerant legumes. We'd suggest Achieve or Wimmera ryegrass for winter bulk, plus Casbah Biserrula or Santorini Serradella to broaden the legume base. Serradellas are generally low bloat risk, and we can build a Custom Mix for your paddock.

How should I graze a new serradella pasture in its first year?

In the first year, we recommend grazing lightly and letting the stand flower and set seed to build the seed bank. Serramax Serradella is hard seeded and regenerates strongly, but only if enough seed is set early on. Its semi-erect habit makes it easy for stock to access once established.

Is Serramax Serradella a new variety?

Yes, Serramax is a new WA-bred yellow serradella in our range. It's early flowering and hard seeded, with a semi-erect growth habit and faster hard-seed breakdown for strong regeneration. It suits acidic sands and sandy loams in 300mm+ rainfall, sown at 6 to 10 kg/ha.

Serramax vs Fran2o, which is better for my farm?

Serramax is a yellow serradella with strong regeneration, waterlogging tolerance and suitability as a permanent pasture. Fran2o is a pink-flowered French serradella suited to summer sowing in pod, flowering at around 90 days. Both suit acid sandy and loamy soils; choose Serramax for a long-term regenerating pasture.
